Using VARA

VARA can be used for either HF or VHF/UHF (FM) and the website can be found here.

NOTE: most antivirus will trigger a false-positive with this software. You may encounter issues unzipping or even using the software. To install disable your antivirus for ~5 minutes and run as administrator. Once installed make sure the path to VARA (I used the defaults of C:\VARA\ for HF and C:\VARA FM\ for VHF/UHF) is in your antivirus exception list.
